Title: Time delay device for paging system and paging system using the same
Inventor: FUJII MASATO
IPC: H04W84/02
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To maintain synchronization accuracy by matching a multiplexer with an existing installation in the case of introducing the multiplexer to a paging system. SOLUTION: A multiplexer MUX 40 and a demultiplexer MUX 42 are provided between a central control station 10a and a monitor controller slave set 18a and signals resulting from multiplexing plural paging signals are sent through a transmission line consisting of exclusive lines. On the other hand, no multiplexer 40 or the like is provided between a central control station 10b and a monitor controller slave set 18b. Instead, a paging system delay device DLY 44 is provided to provide a time delay equivalent to that by multiplexing/demultiplexing processing to the paging signal to provide a time delay similar to a time delay resulting from the multiplexer 40 and the demultiplexer 42. Thus, the time delay at the side introducing the multiplexer and that at the side without introducing the multiplexer are set equally to smooth the operation of the paging system.

Title: Method for detecting interlayer slippage of strip coil
Inventor: TADA YOSHIO
IPC: G01B21/00
Filed: 1987-03-06
Abstract: PURPOSE:To discover the generation of an interlayer slippage on a strip coil at an early stage and to constrain a defect to the min. extent by measuring the length or diameter of a metal strip wound or rewound on each one rotation of a rotary reel and comparing the measurement values at the previous time and this time. CONSTITUTION:A plate thickness value (t) set in advance by a plate thickness setter 10 is inputted in an arithmetic unit 9. The winding length of a metal strip S between the rotation n-1 and the rotation (n) of a tension reel 1 is calculated based on this plate thickness value (t), the count value Pn inputted from an up counter 7 and the previous time count value Pn-1 inputted from a latch circuit 8. Whether an interlayer slippage is caused on the strip coil SC formed on the tension reel 1 is decided based on the above. If the generation of the interlayer slippage is decided, the defect can be prevented at an early stage by outputting a decision signal DS to an alarm device or line control device 11.

Abstract: PROBLEM TO BE SOLVED: To provide an electromagnet for electromagnetic relay which can remove deterioration of magnetic characteristics caused by magnetic distortion, can eliminate variations in the height of an ion core, can have stable operational characteristics, and can facilitate tolerance management, and also to provide a method for manufacturing the magnet. SOLUTION: When an insert hole 22 is made for insertion of an iron core 10 into a flange 21 of a yoke 20, a slit 24 is formed in the yoke 20 to communicate with the insert hole 22 to make the diameter of the hole 22 variable, and the hole 22 is set to be smaller in diameter than the iron core 10. The iron core 10 is fitted into the hole 22 with its diameter enlarged, so that a resilient returning force of the flange 21 causes the iron core 10 to be tightened, thus joining the flange to the core 10. When the hole 22 is set larger in diameter than that in the core 10, further the core 10 is inserted into the hole 22, and thereafter plastic deformation of the flange 21 causes the diameter of the hole 22 to be reduced, so that the core 10 is tightened, realizing firm joining of the core 10.

Moreover, an electrophotographic sensitive body having improved adhesion of the photosensitive layer, improved density difference of picture image, and a picture image improved in defective quality, is obtd. The effect of injection into positive holes is improved further by combining an effect of crystallization of an interface between the photosensitive layer and the substrate.
